It might be tough doing a knockouttornament with only 9 people. We need 16 people atleast. How about i change the tournament into a "league" Were we all play eachother 2 times and the top 4 plays semi final and the final? - Then we can start the tournament tomorow.
And about which teams, i personally dont really care, as long its in the same star-level i am fine. But if we need a restriction, i'd say 4 star teams only for variation.
